Description of PT4115:

The PT4115 is a step-down constant current source with a continuous inductor current conduction mode, designed for driving one or more series-connected LEDs. The input voltage range of PT4115 is from 8V to 30V, with adjustable output current, up to a maximum of 1.2A. Depending on the input voltage and external components, the PT4115 can drive LEDs with power up to tens of watts. The PT4115 features an integrated power switch, utilizes advanced current sampling to set the LED average current, and can accept analog dimming and a wide range of PWM dimming via the DIM pin. When the voltage of DIM is below 0.3V, the power switch turns off, and the PT4115 enters a standby state with a very low operating current.

PT4115 is available in SOT89-5 and ESOP8 packages.
